HTTPS with QNetworkAccessManager not working

Dave P.

This is a thread that I am trying to get https working in and I can't.. Help please!

MyHttpsThread::MyHttpsThread(QObject *parent) :
QThread(parent)
{
}

MyHttpsThread::~MyHttpsThread()
{
m_mutex.lock();
m_quit = true;
m_mutex.unlock();
wait();
}

void MyHttpsThread::startMyHttpsThread(void)
{

const QMutexLocker locker(&m_mutex);
//m_serror = error;


if (!isRunning())
    start();

}

void MyHttpsThread::run()
{
qDebug() << "MyHttpsThread started";

QNetworkRequest netRequest;
QSslConfiguration sSlConfig;

netManager = new QNetworkAccessManager();

sSlConfig.setDefaultConfiguration(QSslConfiguration::defaultConfiguration());
sSlConfig.setProtocol(QSsl::TlsV1_2);
netRequest.setSslConfiguration(sSlConfig);
netRequest.setUrl(QUrl("https://tlsinfo.nails.eu.org"));

connect(netManager, SIGNAL(finished(QNetworkReply*)), this, SLOT(replyFinished(QNetworkReply*)));
//connect(netManager, SIGNAL(error(QNetworkReply*, QNetworkReply::NetworkError&)), this, SLOT(errorReturned(QNetworkReply*, QNetworkReply::NetworkError&)));
connect(netManager, SIGNAL(sslErrors(QNetworkReply*, const QList<QSslError>&)), this, SLOT(onSslErrors(QNetworkReply*, const QList<QSslError>&)));
netManager->get(netRequest);

while (!m_quit) {
    QThread::msleep(1);
}   // while (!m_quit)

}

void MyHttpsThread::replyFinished(QNetworkReply* reply)
{
int ii;
QByteArray data = reply->readAll();
ii = 0;
}

void MyHttpsThread::errorReturned(QNetworkReply*, QNetworkReply::NetworkError &err)
{
int ii;
ii = 0;
}

void MyHttpsThread::onSslErrors(QNetworkReply* reply, const QList<QSslError> &errors)
{
int ii;
ii = 0;
}

@Dave-P. said in HTTPS with QNetworkAccessManager not working:

I am trying to get https working in and I can't..

Please provide more details: What doesn't work? What error messages do you get?

Anyway, Qt requires OpenSSL to use HTTPS. Have you installed OpenSSL 1.0.2 and put it in a PATH that your app can find?

@JKSH Hi,

I did install the latest openssl but because of homebrew issues it had to be installed at: /Users/davidpatton1/scratch/openssl

Here is the openssl version -a output...
OpenSSL 1.1.1-pre9-dev xx XXX xxxx

ENGINESDIR: "/usr/local/lib/engines-1.1"

By not working I mean that neither the: void MyHttpsThread::replyFinished(QNetworkReply* reply) nor the void MyHttpsThread::onSslErrors(QNetworkReply* reply, const QList<QSslError> &errors)

routines are ever hit. Opening https://tlsinfo.nails.eu.org in my browser works fine..

Thanks..

OpenSSL v1.1 is incompatible with OpenSSL v1.0.2.

For now, try installing v1.0.2 to check if it works.

After that, if you want to use v1.1, I think you need to rebuild Qt to link against OpenSSL v1.1
